STOCKHOLDERS' EQUITY

Components of accumulated other comprehensive loss

Components of accumulated other comprehensive loss were as follows at December 31:

	2015		2014		2013
	(in thousands)
Pre-tax amounts:
Unrecognized net periodic benefit costs(1)	$	(35,231)	$	(30,140)	$	(17,044)
Interest rate swap		(897)		(576)		—
Foreign currency translation		(2,379)		(1,216)		(863)
Total	$	(38,507)	$	(31,932)	$	(17,907)
After-tax amounts:
Unrecognized net periodic benefit costs(1)	$	(25,497)	$	(22,387)	$	(14,386)
Interest rate swap		(545)		(350)		—
Foreign currency translation		(1,454)		(742)		(526)
Total	$	(27,496)	$	(23,479)	$	(14,912)

⁽¹⁾ The increase in unrecognized net periodic benefit costs for 2015 primarily reflected the impact of increases in the unrecognized net actuarial loss of $4.2 million ($2.5 million after‑tax) related to the nonunion defined benefit pension plan, primarily due to the difference in actual return on plan assets versus the assumed return offset, in part, by pension settlement expense and amortization of net actuarial losses.The increase in unrecognized net periodic benefit costs for 2014 reflected the impact of increases in the unrecognized net actuarial loss $8.3 million ($5.1 million after-tax) related to the nonunion defined benefit pension plan and $5.2 million ($3.2 million after‑tax) related to the postretirement health benefit plan, primarily due to decreases in the discount rates used to remeasure the plan obligations. The nonunion defined benefit pension plan is discussed further in Note I.
